Buckner (2-1) allowed four hits, struck out five and walked two. The right-hander, who began the season in the Diamondbacks' bullpen, has allowed six earned runs over 18 1-3 innings in three starts since being recalled May 22 from Triple-A Reno.

Tony Pena followed Clay Zavada and Juan Gutierrez out of the bullpen and gave up RBI singles in the ninth to Rafael Furcal and Juan Pierre before posting his first save of the season. Closer Chad Qualls was unavailable because of stiffness in his right forearm.
